Sorry, premature submit and no way to edit or delete ticket.

I mean to add this common use case:

my_program | tee -a logfile | growlnotify -t
or
my_program | grep 'string of interest' | growlnotify -t

On every run, even if my_program produces no output or the grep statement 
doesn't
match, growlnotify produces an empty notification. One must add another layer of
logic using something like awk or perl to only call growlnotify when necessary.

Seems reasonable. Those who want to send a notification with an empty 
description could use -m ''.
